This Hygrometer works great for measuring humidity in any incubator. The humidity gauge does not only display the humidity percent, it shows you what range you should keep your humidity at for each phase of the incubation cycle. This hygrometer is also a replacement for the hygrometer in the No. 1140 Incubator Warehouse IncuView Incubator Lid (Current model only - Does not replace the old dial hygrometer).
